The rectangle shown has an area of (y^2+8y+15)m^2 what is the width of the rectangle

Free_Kalibri [48]

If the dimensions are "nice" factors of the quadratic, and if y > -3, we have
.. area = (y +3)(y +5)

y+5 is greater than y +3, so we take the width to be ....
.. width = y+3

Simplify completely x^2+4x-5/5x^2-8x+3

arlik [135]

Answer:

$\boxed{\bold{\frac{x+5}{5x-3}}}$

Explanation:

[ Step One ] Factor $\bold{x^2+4x-5}$

$\bold{x\left(x-1\right)+5\left(x-1\right)}$

[ Step Two ] Rewrite Equation

$\bold{\frac{\left(x-1\right)\left(x+5\right)}{5x^2-8x+3}}$

[ Step Three ] Factor $\bold{5x^2-8x+3}$

$\bold{\left(x-1\right)\left(x+5\right)}$

[ Step Four ] Rewrite Equation

$\bold{\frac{\left(x-1\right)\left(x+5\right)}{\left(5x-3\right)\left(x-1\right)}}$

[ Step Five ] Cancel Out Common Factor $\bold{x-1}$

$\bold{\frac{x+5}{5x-3}}$

$\boxed{\bold{Mordancy}}$

Sean paints 8/15 of a fence in 1 hour. He paints 3/10 of the fence less in the second hour. What fraction of the fence did he pa

a_sh-v [17]

Answer: $\frac{3}{10}$

Step-by-step explanation:

Given

Sean paints $\frac{8}{15}$ of a fence in 1 hour

Sean paints $\frac{3}{10}$ part less in the second hour

So, fraction he paints in the second hour = $\frac{8}{15}-\frac{3}{10}=\frac{16-9}{30}=\frac{7}{30}$

Paint in 2 hours = $\frac{8}{15}+\frac{7}{30}=\frac{16-7}{30}=\frac{9}{30}$

= $\frac{3}{10}$

No, he did not finish his job
